A provider tells the nurse a client with a peptic ulcer is being placed on a proton pump inhibitor. Which medication would the nurse anticipate the provider ordering?

A. A single IV line allows simultaneous administration of multiple drugs, but compatibility must be confirmed. Morphine and ketorolac are generally compatible for IV administration, but a dedicated line is preferred to avoid potential precipitation or chemical interactions that could reduce efficacy or cause harm. A dedicated line ensures each drug is delivered without interference, aligning with safe administration practices for this patient’s pain management.

B. A Y-site IV configuration allows drugs to mix at the infusion site, which could lead to incompatibility. Morphine, an opioid, and ketorolac, an NSAID, have different chemical properties, and while no major incompatibility is documented, using a Y-site risks minor interactions or reduced efficacy, making it less ideal than a dedicated line for this patient.

C. Flushing the IV line ensures patency but does not address drug compatibility. Morphine and ketorolac administration through the same line without a dedicated setup could lead to precipitation or reduced effectiveness, especially if not flushed properly between doses. This option is insufficient for ensuring safe delivery in this context.

D. Ketorolac, an NSAID, can cause gastrointestinal or renal side effects but does not directly interfere with morphine’s action. However, simultaneous administration through the same IV line could risk chemical incompatibility, such as precipitation, which could obstruct the line or reduce drug efficacy, making this a critical consideration for the patient’s IV setup.

E. Morphine, an opioid, provides analgesia but does not inherently interfere with ketorolac’s action. The concern lies in their co-administration through the same IV line, where potential chemical interactions could occur, supporting the need for a dedicated line to ensure both drugs are delivered effectively for the patient’s pain control.

F. Heparin, an anticoagulant, is not mentioned in the provider’s orders. Interference with heparin is irrelevant here, as the focus is on morphine and ketorolac compatibility. This option is incorrect, as it does not address the patient’s medication regimen or IV administration concerns.

G. Saline is used for flushing IV lines to maintain patency, not as a primary drug. It does not interfere with morphine or ketorolac but is irrelevant to the question of drug interference, making this option incorrect for the patient’s pain management context.

H. Precipitation occurs when incompatible drugs mix, forming insoluble particles that can clog the IV line or reduce drug efficacy. Morphine and ketorolac have a low risk of precipitation, but a dedicated line minimizes this risk, ensuring safe and effective delivery, making this a correct consideration for the patient’s IV setup.

I. Flushing between drug administrations prevents mixing but does not eliminate the need for a dedicated line. While flushing reduces interaction risks, it is less reliable than a dedicated line for ensuring morphine and ketorolac are administered without interference, making this option less optimal for the patient’s needs.

Choice A reason: Frequent skin assessments allow early detection of pressure injury signs, such as non-blanchable redness or skin breakdown. By identifying at-risk areas like the sacrum or heels, nurses can implement preventive measures promptly. This reduces tissue ischemia from prolonged pressure, preventing progression to ulcers by ensuring timely intervention to protect skin integrity.

Choice B reason: Frequent turning and positioning relieve pressure on bony prominences, reducing ischemia and tissue damage. Repositioning every 2 hours promotes blood flow, preventing prolonged compression of capillaries, which leads to hypoxia and necrosis. This is a cornerstone of pressure injury prevention, especially in immobile patients with limited tissue perfusion.

Choice C reason: Optimizing nutrition ensures adequate protein and micronutrient intake, essential for tissue repair and maintenance. Malnutrition impairs collagen synthesis and immune function, increasing susceptibility to skin breakdown. Adequate caloric and protein intake supports skin integrity, reducing the risk of pressure injuries by enhancing tissue resilience and healing capacity.

Choice D reason: Maintaining the head of the bed at a 45-degree angle increases shear forces on the sacrum and coccyx, potentially exacerbating pressure injury risk. While it may aid respiratory function, it does not directly prevent pressure injuries and may contribute to skin breakdown in immobile patients due to increased frictional forces.

Choice E reason: Inspecting the sacrum for blanching is part of skin assessment but is not an intervention to reduce incidence. Blanching indicates intact capillary perfusion, but non-blanchable redness signals early damage. While useful for staging, it is a diagnostic step, not a preventive measure like repositioning or nutrition, which actively reduce pressure injury risk.
